Solution is:

   - (void)setParentController:(UIViewController*)parent{
 [self setValue:parent forKey:@"_parentViewController"];

PS: Don't use "setParentViewController" as method name, because this method exists in private API and Apple say: "The non-public API that is included in your application is setParentViewController:.
